Previously the CurrentX11TimeGetter and CurrentWindowsTimeGetter classes acted
as functors with a single operator() method. In preparation for handling clock
skew, this patch refactors these two helper classes into regular classes with
two named methods:
GetCurrentTime which matches the existing operator() method, and
GetTimeAsyncForPossibleBackwardsSkew which will be used when possible
backwards skew is detected to fetch the current time asynchronously.
Some renaming is also included to match the expanded role of these classes.
This just moves the code from widget/windows/nsWindow.cpp to a template class in
widget/xpwidgets/WrappingTimeConverter.h so that we can reuse this code for
other platforms (GTK at least).
The creation of the surrogate native window in the child NPAPI process was
failing when then sandbox was at low integrity, because the parent is from the
chrome process, so at medium integrity.
Instead of making an IPC call to get the parent, we now create the window upfront
and send it in an IPC message to be parented in the chrome process.
This is done with asynchronous messaging.
The code was for improving fullscreen transition. However, it doesn't seem to
be an improvment anymore. Instead, it causes various bugs like bug 649067,
bug 646374, bug 1053783. Also see bug 634586 comment 33 which shows that this
code causes performance issue on slow machine. According to my test, removing
this code could improve the speed switching to fullscreen from normal mode.

This conversion was done with the script:
find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \
egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \
xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \
-e 's/TemporaryRef</already_AddRefed</g'
Manual fixups were performed in the following instances:
- We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself
into already_AddRefed.
- The following files had explicit Move() calls added to make up for the lack
of a copy constructor on already_AddRefed:
dom/base/ImageEncoder.cpp
dom/media/MediaTaskQueue.{h,cpp}
dom/media/webaudio/PannerNode.cpp
- A redundant overload for MediaTaskQueue::Dispatch was deleted.
- A few manual fixups were required in mfbt/tests/TestRefPtr.cpp.
- Comments, using declarations, and forward declarations relating to
TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to
already_AddRefed.
